# Cross-platform entrypoint for running a local Warp build.
#
# On macOS this delegates to `./script/macos/run`, which builds and runs Warp
# as a real `.app` bundle (with code signing, plist updates, etc.). On Linux
# and Windows it invokes `cargo run` directly for the appropriate binary.
#
# This script owns all cross-platform setup (running install_channel_config,
# detecting internal vs OSS builds, and mapping legacy `--features` entries
# to environment variables), so platform-specific scripts can assume those
# values are already provided via environment variables.
